REEP1 contributes to the shaping of the endoplasmic reticulum (ER) through conserved transmembrane hairpins (THs) and a long C-terminal amphipathic helix. Its loss-of-function causes spastic paraplegia due to degeneration of axons of cortical motoneurons projecting to spinal motoneurons. Patients wi...
